J OHN ALEXANDER SIPARBGV AND VI'ILLIABI .aiI-LRLE, CF .EDGEWICK, ALBERTA, CANADA.

An lication filetl June 16 To (415 whom it may) concern:

Be it known that we, JOHN ALEXANDER ii -111511101X and YfrnLr-mr Hanna, both residing at Sedgewick, in the Province of Alberta,

anada, both subjects of the King of Great Britain, have invented certain new and useful Improvements in Cattle-Guards, of which the following is a specification.

Our invention relates to improvements in cattle guards and one object of the invention is to provide a cattle guard which will not project above the ties, and which will not have to be removed for the winter season. Another object of the invention is to construct a cattle guard which will prevent stock crossing from the public road on to the right of way of the railroad, and without injury to the animal, as it is impossible for the .animal to get stuck in the guard, or the pit thereunder, and in the following specification and the drawings forming part thereof, we shall disclose our invention, and what we claim as new will be set forth in the claims forming part of this specification.

Figure l is a plan view of our cattle guard.

Fig. 2 is a vertical cross section on the line 22, Fig. 1, and Fig. 3 isan elevation of either end of the guard.

In the drawings like characters of reference refer to the same parts.

A pit A is formed in the right of way, and at each side of the pit, and extending transversely of the rails B are placed sills C and D, substantially on the same level. The sill C is supported by the ballast at the topof the sloping wall E of the pit A. F and G are balks or timbers forming a foundation to support the sill D.

Formed in the sill D are a number of mortises 2, vertically disposed and in these mortises are supported the ends 3 of the stringers 4. The ends 5 of the said stringers are suitably coupledto the posts 6. which posts are supported in the ballast, and at the bottom of the sloping wall E.

It will be observed that the stringers i are spaced apart, as are also the posts 6, and that the guard extends beyond the outer side of the said rails. Tie timbers 7 are secured at each end of the guard to the sillsC and D, and these tie timbers if desired may be also coupled to certain of the upright posts 6.

If desired sleepers 8 may be associated Specification of Letters Patent. Patented Sept. 28, 1920.

with the sills C and D after any suitable manner, though it must be understood that these sleepers may be omitted if desired.

It will be observed that portion of the pit A 1s open, and that the other portion there of is covered by the stringers 4L.

The posts 6 and stringers 4 are shown as constructed to provide half laps, a well known construction, and through the said laps is passed the fastening means employed. The preferred fastening means comprises bolts 9 provided with nuts 10 and heads 11. interposed between the said heads and bolts and the posts 6 and stringers 4 are washers 12.

Suitable fastening means for holding the tie timbers 7 to the sills C and D may be in the form of wood screws 13.

Obviously the sill D and balks F and G may be suitably secured together by any means well known in the art.

The open part of the pit will effectively prevent an animal succeeding in stepping on to the stringers 4, and should the animal unfortunately fall into the open part of the pit, because of the sloping wall E thereof, it can climb out of the pit.

The location of the posts 6 at the bottom of the sloping wall E will effectively prevent the animal from getting into the cov ered portion. of the pit.

Obviously the sloping wall E may be faced with cement or cobble-stones, or boards, but since there is no invention in so facing the said sloping wall, such facing is not illustrated in the drawing.

Under circumstances that'may arise in building the guard, it may not be always possible to use the sloping wall E, and therefore our claims are not in all respects confined to a pit made as described.

What we claim isf 1. A cattle guard placed over a pit having an inclined rear wall comprising sills located at each side of said pit and extending transversely of the rails; a plurality of spaced vertical posts mounted in said pit at the foot of said sloping wall, and a plurality of stringers each supported at one end by one of said sills and at the other end by one of said posts thus leaving the said sloping wall uncovered. as set forth.

- 2. A cattle guard placed over a pit having an inclined rear wall, comprising sills located at each side of said pit and extend- 1 ing transversely of the rails; a plurality of sloping Wall uncovered, and tie timbers at 7 each end of the'guard to couple the said sills together, as set forth.

3. A cattle guard placed over a pit having 7 an inclined rear Wall, comprising sills located at each side of said pit and extending V transversely of the rails; a plurality of spaced vertical posts mounted in said pit and located so as to be well spaced from one of said sills thus leaving a portion of-said pit unoccupied; a plurality of stringers each supported at one end by one of said sills,

and at the other end by one of said posts,

as set forth. 7
